I am not sure! If you plain deasigned the peaks, i.e. stripped all assignments from them, then the resonances will still be there. In the Browse Resonances popup do Delete orphans. If you have a set of peaks that you have mis-assigned, but still believe to be associated with a single spin system, then the more "correct" thing to have done within the analysis way of thinking about the data would have been to just break the spin system -> residue assignment. -- Dr. Brian O.
